SIDE BEARING FOR CABS.

Specification of Letters Patent.

Patented Oct. 21, 1919.

Application filed September 28, 1918. Serial No. 256,016.

To all whom it may concern:

Be it known that l, EDWIN 1V. WEBB, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Side Bearings for Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in side bearings for cars and the like; and, to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings Figure 1 is a plan view of the improved side bearing;

Fig. 2 is a view partly in elevation and partly in longitudinal vertical section taken substantially on the irregular line 22 of Fig. 1; and

Fig. 3 is a transverse vertical section takenon the line 3-3 of Fig. 1.

The numerals 4 and 5 indicate, respectively, the truck bolster and the body bolster of a railway car.

The improved side bearing is carried by the truck bolster 4 and includes a cast rectangular housing 6 with an open top. Cast with the lower portion of the housing 6, are three horizontally disposed ears 7, having bores 8, through which rivets. or other fastening means, not shown, are passed to rigidly secure the side bearing to the truck bolster.

In the inner faces ofthe sides of the housing 6, is a pair of opposite channels, each of which affords a pair of reversely inclined camways 9. These camways 9 are upwardly inclined from the longitudinal center of the housing 6 and, at the junction of'their lower surfaces, is formed a pair of axially alined segmental notches or depressions 10. Also formed in the sides of the housing 6, is a pair of pin passageways 11 that are axially alined with the segmental notches 10 and are of the same diameter.

- In the ends of the housing 6, on the bottom thereof, is a pair of lugs 12 and 13 notches l4 and 15, respectively.

having in their ends, which face each other,

It is important to note that the notch 15 is made considerably deeper than the notch 14, for a purpose that will presently appear. On

the bottom of the housing 6, is a removable face of the bottom of the housing 6 is correspondingly formed to receive said plate.

The wearing plate 16. is held in position by the notches 14 and 15 in the lugs 12 and 13. It will be noted that the depth of the notches 15 is suficient to permit the entrance of the wearing plate 16 into said notch and the notch 14 by endwise and lateral movements thereof. To hold the wearing plate 16 in the notches 14 and 15, a cotter'pin 17 is inserted through alined bores 17 in the lug 13 and bottom of the housing 6, and so positioned as to cause said cotter pin to extend through the notch 15 between the body of the lug 13 and. the

wearing plate 16.

To secure the roller 18 in the housing 6, there is provided a rolling centering pin 19 which extends through-an axial opening 20 in said roller with its ends extending into the camways 9. The diameter of the pin 19 is relatively small with respect to the diameter of the axial opening 20 in the roller 18 to permit free radial movements of the roller 18 and pin 19, with respect to each othenv The pin 19 is also of such diameter as to permit the same to be insorted into the housing '6 or removed therefrom through either one of the bores 11,' before the wearing plate 16 is positioned under the roller 18.

In positioning the wearing plate 16 under the roller 18, said roller is lifted sufiiciently to carry the pin 19 out of alinement with the bores 11, and thereby secure the same against removal from the housing 6. The positioning of the wearing plate 16 under the roller 18 not only lifts the pin 19 out of alinement with the bores 11, but also lifts said pin out of the notches 10 and into a position where the same may be rolled in either direction onto the inclined camsaid plate and in which case, the upper surways 9, under the action of the rolling movement of the roller Ben the wearing plate 16.

The pin19, in addition to locking the roller 18 in the housing 6, normally rests on the roller 18 at the lowermost surface of its axial opening 20 andv acts as a common weight to return said roller to a central or normal position. It will be noted that the camways 9 diverge materially from the underlying inclined surfaces of the wearing plate 16 and, as the roller 18 travels upward on either of the inclined surfaces of said wearing plate, the pin 19 is carried thereby upward onto the overlying camways 9 and engages said roller considerably above its normal position with respect thereto.

In case the roller 18 is engaged by the body bolster 5, when the car truck is on a curve, said roller will be moved upward on one of the inclined surfaces of the wearing plate 16 and the pin 19 will be moved therewith upward onto the respective overlying camways 9. In case the body bolster continues to rest upon the roller 18 until -the car truck passes beyond the curve, said roller will be returned to normal position under the action of the two bolsters, with respect to each other. But if the body bolster should lift from the roller 18, while the same is on one of the inclined surfaces of the wearing plate 16, said roller will immediately roll down said surface to normal position. At the same time, the pin 19, held on the respective camways 9 by the roller 18, will act as a counterweight and roll down said camways and thereby assist in returning said roller to normal position.

In assembling the improved side bearing, the roller 18 is first placed in the housing 6 and supported on the bottom thereof. In this position of the roller 18, the lowermost surface of its axial opening 20 is substantially in alinement with the lowermost surfaces of the bores 11. The pin 19 is then inserted through one of the bores 11 andaxial opening 20 in the roller 18 with its ends resting in the notches 10. The roller 18 is then'lifted into a position as high as v the pin 19 in the camways 9 will permit.

\Vhile the roller 18 is thus lifted, the wearing plate 16 is inserted into the housing under said roller and into the notch 15. This notch 15 has suflicient depth to permit the wearing plate 16 to pass the lug 12 and rest on the bottom of the housing 6. An endwise movement of the wearing plate 16 toward the left will cause the same to enter the lock notch 11. The cotter pin 17 is then inserted into the bores 17 to hold the wearing plate 16 interlocked with the lugs 12 and 13.

What I claim is 1. The combination with a housing hav- 'of reversely inclined camways that diverge in respect to said wearing surface, of'a roller having an axial opening supported on the wearing surface, and a rolling centering pin extending into the axial opening in the roller with freedom for radial movement with respect thereto and arranged to travel on the camways.

4 The combination with a housing having reversely inclined wearing surfaces and a pair of reversely inclined camways diverging in respect to said wearing surfaces, of a roller having an axial opening arranged to travel on the wearing surfaces, and a rolling centering pin extending into the axial opening in the roller with freedom for radial movement with respect thereto and arranged to travel on the camways.

4. The combination with a housing having reversely inclined wearing surfaces and oppositepairs of reversely inclined camways diverging in respect to the wearing surfaces, a roller arranged to travel on the Wearing surfaces, and a rolling centering pin extending through the axial opening in the roller with freedom for radial movement with respect thereto and with its ends arranged to travel on the camways.

5. The combination with a housing having a passageway, of a roller having an axial opening adapted to be alined with said passageway, a rolling centering pin adapted to be inserted through said passageway and the axial opening in the roller, anda wearing plate adapted to be inserted under the roller to lift the rolling centering pin out of alinement with said passageway.

6. The combination with a housing having a passageway, of a roller having an axial opening adapted to be alined with said passageway, a rolling centering pin adapted to be inserted through said passageway and the axlal opening in the roller, a wearing plate adapted to be inserted under the roller to lift the rolling centering pin out of alinement with said passageway, and means for securing the wearing plate in position under the roller.

7. The combination with a housing having a pair of opposite inclined camways and a passageway extending into one of saidcamways, of a roller having an axial opening adapted to be alined with said passageway,

opening in the roller with its ends on said cainways, and a Wearing plate adapted to be inserted under the roller to lift the pin out of alinement with the passageway.

8. The combination with a housing having in its sides a pair of inclined cainways, a passageway extending into one of said caniways, and a pair of lock notches in the ends of the housing,-one of said notches having a greater depth than the other thereof, of a roller having an axial opening adapted to be alined with said passageway, a rolling centering pin adapted to be inserted through said passageway and the axial opening in the roller, a wearing plate adapted to be inserted under the roller and into said notches to lift the pin out of alinement with said passageway, and a cotter pin extending through the lock notch having the greatest depth to hold the wearing plate against removal therefrom.

9. The combination with a housing having a passageway, of a roller having an axial openingadapted to be alined with said passageway, a lock pin adapted to be inserted through said passageway and the axial opening in the roller, and a wearin plate adapted to be inserted under the roller to lift the look pin out of alineinent With said passageway.

In testimony whereof I aflix my signature in presence of two witnesses.
